Response:

There is no evidence to support such a claim. Fantastic creatures
appear in folklore from all times and places. There is no reason to
believe that the ancient Hebrews would be different.

The "tail like a cedar," which creationists think indicates a large
dinosaur, is not even a real tail. "Tail" was used as a euphemism in
the King James version. A more likely translation for the phrase is,
"His penis stiffens like a cedar" (Mitchell 1987). The behemoth was
probably a bull, and the cedar comparison referred to its virility.
